“…A possible explanation for the results of this study is that glossing difficult vocabulary helps learners acquire their meaning. This was proved by some studies (e.g., Al-Ghafli & Hussain, 2011;Arpaci, 2016;Azari, 2012;Azari, Abdullah, Heng, & Hoon, 2012a;Ghabanchi & Ayoubi, 2012;Ghahari & Heidarolad, 2015;Huang, 2010;Jung, 2016;Ko, 2012;Salehi & Naserieh, 2013;Todd, 2014;Tong, 2017;Zhao & Ren, 2017). This also goes along with Barcroft's (2015) belief that activities which introduce the meanings of words to learners in the early phase of learning the words enhance the acquisition of word meanings.…”
